W/YLNESSES ATTORNEYS IRVING I. KREMER, OF NEW YORK, N. Y.

NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented June 11, 1907.

Application filed February 12,1907. Serial No. 356,956.

To all whom it may concern:

Be it known that I, IRVING I. Knmina, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved N on-Re'lillable Bottle, of which the following is a full, clear, and exact description.

This invention relates to certain improvements in bottles, and more particularly to an improved form of plug adapted to be secured within the mouth of a bottle whereby the bottle is effectively prevented from being refilled. The plug is so secured in place that it is impossible to remove the same, and the mechanism within the plug is so constructed that liqu d may readily flow out of the bottle through said plug but it is impossible for liquid to be forced into the bottle. This mechanism is also so constructed that the insertion of a wire or other tool to hold the parts in their open position to permit the refilling of the bottle is rendered impossible.

The invention consists in certain features of construction and combination of parts, all of which will be fully set forth hereinafter and particularly pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures, in which Figure 1 is a central longitudinal section through a bottle provided with my improved plug, said section being taken on tie line 1'1 of Fig. 2; and Fig. 2 is a transverse section through the device, said section being taken on the line 22 of Fig. 1.

My improved device is adapted for use in connection with any suitable form of hottle, and may be secured within the neck of said bottle in any suitable manner. In the particular form of my invention disclosed in the accompanying drawings, I provide the bottle neck 10 with inwardly-extending screw threads 11 at a point spaced a short distance from the mouth of the bottle and extending inwardly from the wall of the bottle neck. Closely fitting within the bottleneck, I provide a special form of plug 12 having screw threads 13 adapted to engage with the threads 11 of the bottle neck for holding the plug in the desired position. Any suitable means may be employed in place of the screw threads, and this means would preferably be so constructed as to permit the insertion of the plug but prevent its removal. I/Vhen screw threads are employed as illustrated in the drawings, I preferably coat the outer wall of the plug and the screw threads thereon with a suitable cement or other adhesive before the plug is inserted, whereby the plug after the cement becomes hardened is rigidly and permanently secured in place. The plug is preferably provided with an outwardly-extending flange 14 engaging With the mouth of the bottle, whereby the extent to which the plug is inserted may be limited.

\Vithin the plug I provide special mechanism for permitting the removal of the liquid 1 contents of the bottle but preventing said bottle from being refilled. This mechanism preferably comprises a plurality of outwardly-opening check valves arranged lon gitudinally of the plug and through all of which the liquid must pass before escaping from the bottle. Preferably, each of these valves comprises two oppositely-disposed flat members 15 semi-circular in form and pivoted to a common hinge pin 16 arranged diametrically of the plug and bottle neck. The ends of the hinge pins 16 are embedded within the walls of the plug and may, if (le sired, be secured therein at the time the plug is formed, or may be inserted longitudinally through an opening in the wall of the plug. The inner surface of the plug adjacent each valve, .is provided with an inwardly-extending annular valve seat 17, preferably formed integral with the wall and presenting a smooth surface normally supporting the outer edges of the flaps of the valve when the latter are in their closed position. Directly above each annular valve seat 17 and preferably disposed at points adjacent the ends of the corresponding hinge pin 16, I provide two inwardly-directed lugs 18 formed integral with the wall of the plug. These lugs or projections serve to limit the upward movemerit of the flaps of the corresponding valve,

thus preventing the valves from being opened to more than a limited extent, as illustrated in dotted lines in connection with the upper one of the valves shown in. Fig. 1. The extent to which these valves may thus be opened is sufficient to permit the free egress of the liquid contents of the bottle but prevents a wire or other tool from being inserted past the first valve and employed to open the remaining valves in succession to refill the bottle.

In order that the liquid may flow from the bottle as freely when inclined in one direction as when inclined in another, and also to more efiectively prevent the mechanical opening of the valves, I dispose the successive hinge pins 16 at angles to each other, as clearly illustrated'in the drawings. For preventing the breaking or bending of the top valve whereby access may be gained to the next succeeding valve, I preferably provide an inwardly-directed flange 19 directly above the first valve and extending inward to a dis tance greater than the inward movement of the edges of the flaps of said valve when moved to their open position. This does not materially affect the outflow of liquid as it does not materially reduce the size ofthe outlet opening.

The improved form of plug above described is preferably formed of glass, potteryfor other similar material, whereby the annular valve seats 17, projections 18 and annular flange 19 may be formed integral .with the walls of the plug, but it is evident that various other materials may be employed and many other minor changes made within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In a bottle having a neck, a plurality of annular valve seats disposed in planes atright angles thereto, hinge pins arranged diametrically of said bottle neck, semi-circular flaps pivoted to said hinge pins and adapted to contact with said valve seats, and means.

disposed adjacent each flap and adapted to limit the opening movement thereof.

2. In combination with a bottle having a neck a plurality of valve seats disposed in planes at an angle to the general direction of the bottle neck, hinge pins arranged diametrically of said bottle neck, oppositely disposed flaps pivoted to each of said hinge pins and adapted to contact with said valve seats, and means disposed adjacent each flap and adapted to limit the opening movement thereof.

3. The combination with the neck of a bottle, of a non-removable stopper consisting of a tubular plug having a plurality of annular valve seats integral therewith and disposed in planes at right angles to the bottle neck, hinge pins having their ends embedded within the wall of said plug and arranged diametrically of said plug, semi-circular flaps pivoted to said hinge pins and adapted to contact with said valve seats, and inwardlydirected lugs or projections disposed. adjacent each flap and adapted to limit the opening movement thereof.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

IRVING I. KREMER.
